DIETACHABLE-CALK ATTACHMENT FOR HORSESHOES.

Application illed July 25. 1916.

lhaving applied thereto a supplementary calk structure constructed in accordance with my invention Fig. 2 is a longitudinal section on the line 2-2, Fig. 1; and

Fig. 3 is a transverse section on the line 3 3, Fig. l.

In Figs. 2 and 3 the shoe and the calk- `carrying structure thereon are shown in their normal positions instead of being inverted as in Fig. 1.

In the drawing, l represents an ordinary horseshoe having the usual fixed toe calk A1: and heel ealks Bearing against the inner face of the front end of the shoe is a bar 6 which has upper and lower flanges 62L bearing, respectively, upon the upper and lower sides of the said front portion of the shoe so as to retain the bar 6 in a proper vertical position in respect thereto.

At each end of the bar 6 is a depending boss 7 `which bears against the under face oit the shoe 1 and has secured to it in any suitable way a depending calk 8, preferably sharpened, as shown in the drawing. EX- tending rearwardly from the bar 6 is a plate il having therein longitudinal slots l0, as shown in Figs. 1 and 2, and through each of these slots passes a bolt 1l which is screwed into a bar 12 on the upper face of the plate 9. each ot said bolts l1 being also in pivotal engagement withv the forward end of an arm lai-l. whose rear end is secured to or forms part of a head 14C, said head being in vertical engagement with the iiat upper and lower faces ot the shoe 1 and also in engagement with the inner face of the heel portion oi the shoe and with the front face of the rear calli as shown in Figs. l and 3,

Specification of Letters Patent.

Patented dan. 22, 1918.

Serial No. 111,149,

Between the heads 1-IL is interposed a strut to prevent said heads from moving inwardly toward one another, said strut being` preterablyV composed ot an externally threaded member or bolt 15 and an internally thread ed member or nut 16 in threaded engagement therewith, said member 15 having a squared end engaging` a square socket in one et the heads llt, and said member 16 having a rounded end engaging a round socket in the other head 1st, in order that the member 1G can be turned on the member 15 when it is desired to forcibly thrust the heads 1st apart and into engagement with the inclined inner face of the heel portions of the shoe, as shown in Fig. 1` Secured to and depending from the heads 1iare calks 17, preferably sharpened in the same way as the calks S, as shown in Figs. 2 and 8.

In applying the attachment to a horseshoe the bar 6 is iirst slipped into engagement with the forward end of the shoe, as shown in Fig. 2, and the bolts 11 are then moved rearwardly in the slots 10 of the plate 9 until the heads 14 at the rear ends of the links 13 are jammed tightly against the rear ends of the shoe and the rear calls 5, whereupon the tightening of the bolts 11 will retain the parts in this position and prevent release ot the calli-carrying attachment from the shoe. lVhen such release is desired the bolts 11 are loosened and the bar 6 and heads lil may be moved toward one another until they are tree from engagement with the shoe and can be removed therefrom.

As compared with previous calk-carrying attachments of which I have knowledge, my attachment possesses the advantages of fewness of parts and simplicity and cheapness ot construction, and while it insures iirm grip of the shoe upon a slippery roadway it does not increase the weight of the shoe to an objectionable extent.

I claim:

The combination of a horseshoe with a calli-Carrying attachment comprising a calkcarrying bar having` bosses in vertical engagement with the frontportion of the shoe and having a plate extending rearwardly therefrom and provided with longitudinal slots. heads in vertical engagement with Jthe heel portions of the shoe and having arms projecting .forwardly therefrom, clamping bolts for said arms occupying said slots in the plete, and en adjustable strut for the neme to this Specification, in the presence of heads, sold Strut eompusmg e threaded bolt Vtwo snbscmblng Wltnesses.

in non-1otat1ve engagement mth one oi Saud heads and n. nnt in threaded engagement Y JOSEPH SOHULTZ. with seid bolt :md in l'evoluble engagement Vtnesses: Y with the opposite head. O. L. EVANS,

In testimony whereof, I have signed my VILLIAM EDELMAN.
